Money is by far the last thing on Yosuke's mind, not that he's expecting a transaction to take place here anyway. He bucks up a bit accidentally, definitely too eager, not sure what to do with himself. But he can follow a lead, so he parts his lips to allow Eponine access to his mouth.

He's a little embarrassed to have her stripping his shirt off-he's all ribs underneath. He hasn't had time to gain back the weight that he lost, and he's just plain skinny. But she's a thin girl too, so maybe she'll forgive him. Either way, he trembles and tries not to rut against her. That's definitely no way to impress a girl. Besides, he's hoping she won't realize yet that he's so easily turned on. It's really uncool to act too eager.
